I have seen various wooden grips for the Mustang and Pony in the past, when I had been searching for Beretta and 1911 grips. I don't remember where I saw them, however. I think I was just googling "1911 gun grips" or something similar, and I was just browsing all of the sights that came up.
The gun came out very well. I have not heard of that place before.
I had Springfield hard chrome a 1911 in 1998, and it took 6 months to get it back because the custom shop was so backed up w/ work. They outsourced the hard chroming too, so they didn't actually do it themselves. It came back w/ a flaw on the front strap, but after waiting 6 months, I just put a set of wraparound Hogue grips on to cover it, and it was good enough.
So, I don't have good luck w/ 1911's being hard chromed.
